Tension
In physics, tension is the magnitude of the pulling force exerted by a string, chain, cable, or similar object on another object. It is the opposite of compression. As tension is the magnitude of a force, it’s measured in newtons and is always measured parallel to the string on which it applies. There are 2 basic possibilities for systems of objects held by strings. Either acceleration is zero or the system is there for in equilibrium, or there is acceleration and there for a net force is present. Note that a string is assumed to have negligible mass. Forces
In physics, forces are any influence that causes an object to change in speed, a change in direction, or a change in shape. Forces can be also described by intuitive concepts such as pull or push that can cause an object with mass to change its velocity, to accelerate, or can cause a flexible object to deform. A force has both magnitude and direction, making it a vector quantity.Newtonssecond law, F=ma, was originally formulated slightly different, but equivalent terms: the original version states that the net force acting upon an object is equal to the rate at which its momentum changes. Related concepts to accelerating forces include thrust, increasing the velocity of the object, drag, decreasing the velocity of any object, and torque, causing changes in rotational speed about an axis. Forces which don’t act uniformly on all parts of a body will also cause mechanical stresses, a technical term for influences which cause deformation of matter. While mechanical stress can remain embedded in a solid object, gradually deforming it, mechanical stress in a fluid determines changes in its pressure and volume. Elasticity
In physics, elasticity (or stretchiness) is the physical property of a material that returns to its original shape after the stress (e.g. external forces) that made it deform or distort is removed. The relative amount of deformation is called the strain. What is science you may ask. Science is a way of learning about the natural world. In science you study different things . For example in science you do experiments to know why stuff happens. The first process of science is observation. Observing means using one or more of your senses to gather information. There are two types of observation, quantitative and quanlitative observation. Quantitative observation deals with numbers, or amounts. Quaunlitative observation deals with descriptions that cannot be expressed in numbers. The second process of science is inferring. When you infer your making an inference. Inferring is not guessing. Inferences are based on reasoning from what you already know. Inferences could also be based on assumptions. The next step in the scientific process is predicting. Inferences and predictions are closely related. But predicting means making a statement or a claim about what will happen in the future based on past experience or evidence. Classifying is the grouping together of items that are alike in some ways. For example, in a data table, the team grouped together the type of algae found in each area. In science you make models to make repesentations of complex objects or proccesses. Some models can be touched, such as a map. Others are in the form of mathematical equations or computer programs. Evaluating is the six step in the scientific process. Evaluating involves comparing observations and data to reach a conclusion about them. For example, Dr.Earle would have needed to compare the whale's behaviors with those of the other whales in the group to reach a conclusion. The last part of the scientific method is conducting scientific investigations. Science is a continuous cycle of asking questions about the natural world and looking for answers. A scientific investigation is the way in which scientists study the natural world. First, you ask a question. Then, you figure out a way to find the answer. Finally, you perform the actions necessary to find the answer.
